Well thought out engineering. Factory holes lined up perfectly. VERY basic installation, each side had 3 brackets that attached with 2 bolts each. You put one bolt in halfway, the bracket has an open slot that you set on the bolt then you put the other bolt in. No need for 3 hands! Then you set the bar in place and put in 6 bolts each side. The left side and right side are in different color plastic wrap so it's easy keeping the parts right. The ends are welded closed nicely. Well packed too, no marrs or scratches.
